When it comes to RC buggies, 4WD tends to dominate the modern scene with its sheer traction and performance. But ask any long-time hobbyist, and they’ll tell you there’s something special about RWD (rear-wheel drive) off-road buggies. They may not have the grip or stability of their 4WD cousins, but… Continue reading
In the world of 1/10 on-road RC racing, belt-driven four-wheel-drive cars have earned a reputation for refinement, speed, and tunability. While shaft-driven cars such as the TT-series remain popular as entry points, racers who want to unlock the next level of performance often turn to belt-driven platforms. Among these, the… Continue reading
The Tamiya TT-01 is one of those kits that just about every RC enthusiast has crossed paths with at some point. It’s simple, durable, affordable, and for many people, it was their first taste of on-road RC fun. Out of the box, it’s a 4WD touring car, but one of… Continue reading
On an RC car, the relationship between the pinion gear (on the motor) and the spur gear (on the drivetrain) determines your gear ratio. When you run a larger pinion with a not-so-large spur, you’re gearing the car toward higher top speed at the expense of torque and thermal efficiency…. Continue reading
The Tamiya TT-01 rear gearbox loose problem is a common issue among the TT-01 chassis. This is when the rear gearbox housing aka differential case becomes loose, which can result in drivetrain instability, gear misalignment, or even stripped gears over time. The screws securing the gearbox halves may loosen over… Continue reading
Yes, metal RC car gears are generally SLIGHTLY noisier than plastic gears, although this is often a trade-off for strength and durability. The main reason for the increased noise is that metal gears have a much harder contact surface. Unlike plastic, which naturally absorbs some vibration and softens the gear… Continue reading
To lap RC car gears (i.e., smooth out the gear mesh by controlled wear), you need a safe, mildly abrasive compound that can polish without damaging. Toothpaste works for light break-in runs (1–2 minutes at low speed). Follow these steps: Apply thin layer of compound to gear teeth. Run the… Continue reading
Applying Vaseline (petroleum jelly) to an RC car gearbox is not recommended, and here’s why: 🔧 What Will Happen if You Use Vaseline in an RC Gearbox: ❌ 1. Poor Lubrication Under Load Vaseline is not designed for high-speed mechanical parts. It becomes too thin when warm and doesn’t provide… Continue reading
